Snapshotting brightness of a light

Configuration
1

I need some help debugging a specific hiccup I have with one light used in a scene. Basically, I have automation set up that if the garage door is opened and the kitchen light is below a certain value, then raise the brightness to a specific value for 5 minutes, then go back to the prior brightness.

This automation also turns on the garage lights and others, which work perfectly as they are simple on/off switches for the lights. When I trigger the automation, I create a scene and snapshot the entities. This seemingly works, then I raise the brightness, and when the time comes, I activate the scene.

Now here’s the rub, this particular light supports color warmth and RGB. When I create a scene on it and then activate the scene, it is changing the light from a warm white to a purple. I figure the device is being particular to some of the attributes being saved in the scene. I am trying to figure out a way to tweak the scene or store the value in a script variable for use later. Anyone have thoughts on how to handle a scenario light this?

Here is my automation:
